I have a Weil-Mclain GV-5 that locks out. The control module

Customer Question

I have a Weil-Mclain GV-5 that locks out. The control module was replaced a number of years ago, with modle 1013-200, that has five lights. When it locks out, the Power light flashes, the TSTAT CIRC light stays on, the Limit light stays on, the Limit light stays on, the Press Switch light is off, and the Flaame light flashes. Do you have any suggestions?
